WhatsOpen

WhatsOpen lets you start a WhatsApp conversation with any phone number — even numbers you haven't saved as contacts.

Features:

* Enter a phone number with country code and open WhatsApp directly

* Auto-detect phone numbers from your clipboard

* Browse recent call log entries and open WhatsApp for any of them

* Filter call log by call type and WhatsApp contact status

* Material 3 design with light and dark themes

WhatsOpen requires no network access, contains no analytics, and does not track you. All processing happens on-device.

Permissions:

* Read call log — to show recent calls

* Read contacts — to display contact names alongside numbers
